FREDERICK G. SARGENT AND ALLAN O. SARGENT, OF GRANITEVILLE, MASS.

WOOL-WASHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 330,930, dated November 24:, 1885.

Application filed December 31, 1883. Serial No. 116,122.

To all whom it may concern:

Be it known that we, FREDERICK G. SAR- GENT and ALLAN O. SARG-ENT, of Graniteville, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Wool-WVashing Machines, of which the following is a specification.

Our invention relates to machines for washing wool and other similar fiber; and it consists in arranging and applying perforated endless traveling aprons of wire to convey the fiber through the washing-liquid, substantially as hereinafter described and claimed.

In the drawings, Figure 1 is a longitudinal vertical section of the machine. Fig. 2 is a top plan view of the same.

A is the bowl of the machine, which is provided with a perforated bottom, a, and a pipe, a, for forcing in the washing or cleansing liquid, and a discharge-pipe, a", and valve a, for drawing it off. This bowl is intended to be filled with washing-liquor about up to a level with the axis of the lower squeeze-roll, B. B is the upper squeeze-roll. In suitable positions in the frame we mount the rollers C, G, 0 C 0, and C and carry around them the endless wirescreen aprons D D, so as to enable them to carry the fiber between them downward through the washing-liquid, and thence upward to the squeeze-rolls. These aprons are so arranged as to gradually squeeze and compress the fiber as they carry it farther downward into the liquid and it becomes more perfectly soaked, and thus expel the dirt and grease from it. Being made of woven wire, they afford sufficient adhesive surface to carry the wool along, and at the same time afford the greatest exposure of the surface of the masses of fiber to the soaking in of the liquid, and its subsequent escape as the fiber is compressed, and carrying 01'1" the dirt and impurities.

As is well known, in the washing of wool from the fieece the grease in the wool speedily gives the liquid in the bowl a greasy consistency, and this greasy liquor is found best for washing the wool, as it is not feasible to remove all of the oil from it and leave itin good condition for further working. This greasy (No model.)

consistency of the liquor and fiber renders it very difficult to carry the wool through the liquor upon any form of apron which is made of such material as to present any consider-v able proportion of surface for the wool to rest upon in proportion to its entire area. With a woven-wire apron, however, made with its meshes of the right size, so much of the fiber projects through the meshes and on each side of each wire forming a mesh as to hang the wool over the wire, and the friction thus produced on a great number of such wires prevents the wool from moving or being rolled and felted upon or between the apron or aprons, as when aprons of other materials than wire are used. In addition. the wovenwire apron possesses all the flexibility requisite to enable it to pass over a roller at its delivery end, and by means of the action of this roller in pressing back through the meshes the fiber which has been squeezed through them, the apron at once gives up its burden of wool and allows it to pass onward to the squeeze-rolls without being rolled or felted together while passing through the washing-liquor. The two opposite aprons acting each in this manner further act conjointly to squeeze the wool, :as before described, and deliver it to the squeeze-rolls without allowing it to slip or roll and felt itself together between them.

The wire aprons D D are driven by a pulley, 0, upon the shaft of the roll 0, the gearwheel 0 upon the same shaft, and the gearwhecl 0 upon the shaft of roll 0 What we claim as new and of our invention is 1. In a wool-washing machine, in combination with the bowl A, the endless carryingapron D, adapted to carry the wool through the bowl during the process of soaking and cleansing it, formed of woven wire, and the roller 0, substantially as described.

2. In combination with the bowl A and squeeze-rolls B B, the endless carrying-apron D, adapted to carry the wool through the bowl during the process of soaking and cleansing it, formed of woven wire, substantially as described.

3. In combination with the bowl A, two
